How to convert btus to calories (Btu to cal)

The formula for converting btus to calories is: cal = Btu × 252.19021687207. To calculate the btu value in calories first substitute the btu value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 btu in calories we follow these steps:

cal = Btu × 252.19021687207

cal = 1 × 252.19021687207

cal = 252.19021687207

In other words, 1 btu is equal to 252.19021687207 calories.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 6 btus to calories is:

Understand the conversion formula: cal = Btu × 252.19021687207
Substitute the required value. In this case we substitute 6 for Btu so the formula becomes: cal = 6 × 252.19021687207
Calculate the result using the provided values. In our example the result is: 6 × 252.19021687207 = 1513.14130123242 cal

In summary, 6 btus is equal to 1513.14130123242 calories.

Converting calories to btus

In order to convert the other way around i.e. calories to btus, you would use the following formula: Btu = cal × 0.0039652608749183. To convert calories to btus first substitute the calorie value into the above formula, and then execute the calculation. If we wanted to calculate 1 calorie in btus we follow these steps:

Btu = cal × 0.0039652608749183

Btu = 1 × 0.0039652608749183

Btu = 0.0039652608749183

Or in other words, 1 calorie is equal to 0.0039652608749183 btus.

Conversion Unit Definitions

What is a Btu?

BTU, or British Thermal Unit, is a unit of heat energy commonly used in the United States and some other countries. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure.

In SI units, one BTU is approximately equal to 1,055 joules. It is often used in the context of heating, air conditioning, and energy-related applications, especially in the United States. For example, the heating or cooling capacity of air conditioning systems, as well as the energy content of fuels such as natural gas, is often expressed in BTUs.

For comparison, 1 BTU is roughly equivalent to the energy released by burning a match. In practical terms, it's a relatively small unit of energy, but it's useful for everyday applications involving heating or cooling.

What is a Calorie?

A calorie (cal) is a unit of energy commonly used in nutrition. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius (or one degree Kelvin). In the context of nutrition, the term "calorie" usually refers to a kilocalorie, which is equal to 1,000 calories in scientific terms.

The energy content of food and beverages is often measured in kilocalories, abbreviated as kcal or Cal (with an uppercase "C" to distinguish it from the smaller "cal" used in physics).

In scientific terms, 1 kilocalorie is equal to 4.184 kilojoules (kJ). The conversion factor between kilocalories (kcal) and kilojoules (kJ) is 1 kcal = 4.184 kJ.

In everyday language, when people refer to the number of calories in food, they are usually referring to kilocalories. For example, if a food label says a serving contains 200 calories, it means 200 kilocalories or 200,000 calories in scientific terms.
